A private Europe-based investment group has sold a 96,718-square-foot office building in Miami, Fla., for $28.5 million.

Boston-based Congress Group purchased the property, which is located at 999 Brickell Ave. in the Brickell Financial District.

At the time of sale, the property’s main tenant was Helm Bank, although the building has "exceptional future development potential for office, residential or hotel-related uses," according to a press statement.
